pySim WiKi

pySim-prog is a small command line utility written in python, which is used for programming various programmable SIM/USIM cards.

Supported Cards

1. Install dependencies

sudo apt-get install pcscd pcsc-tools libccid libpcsclite-dev

2. Connected your SIM card reader

3. Plug your programmable SIM card in

4. Check the status of connection by execution of the following command:

pcsc_scan

5. If SIM card reader is recognised then we can expect similar to the below output:

$ pcsc_scan
PC/SC device scanner

6. Exit pcsc_scan : Ctrl+C

7. Get the code of PySIM by entering command:

git clone git://git.osmocom.org/pysim pysim
cd pysim

8. Run the /pySim-read.py to read your SIM card:

./pySim-read.py -p0 or ./pySim-read.py -p1

9. Using sysmoSIM-GR1 and if everything is done correctly, you will see something similar to:

$ ./pySim-read.py -p0 
Reading ...
ICCID: 1791198229180000071
IMSI: 001640000000071
SMSP: ffffffffffffffffffffffffe1ffffffffffffffffffffffff0581005155f5ffffffffffff000000
ACC: ffff
MSISDN: Not available
Done !

9.1. In case of sysmoUSIM-SJS1 SIM card, you will see something similar to:

$ ./pySim-read.py -p0
Reading ...
ICCID: 8988211000000106594
IMSI: 901700000010659
SMSP: ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff
ACC: 0200
MSISDN: Not available
Done !

9.2. In case of SuperSIM/X-sim card, you will see something similar to:

$ ./pySim-read.py -p0

11. Example to program a sysmoSIM-GR1 card

The GRcard SIM is a programmable GSM SIM card. It uses a mixture of TS11.11 / ISO7816-4 and proprietary commands for programming.

In the below example, we are changing the card’s IMSI to 901700000003080, and specify a new set of -n NAME (Operator name), -t TYPE (Card type), -c CC (Country code), -x MCC (Mobile Country Code), -y MNC (Mobile Network Code) and -s ID (Integrated Circuit Card ID) values.

$ ./pySim-prog.py -p 0 -n OpenBSC -t sysmosim-gr1 -i 901700000003080 -c 001 -x 001 -y 02 -s 1791198229180000075
Insert card now (or CTRL-C to cancel)
Generated card parameters :
> Name : OpenBSC
> SMSP : e1ffffffffffffffffffffffff0581005155f5ffffffffffff000000
> ICCID : 1791198229180000075
> MCC/MNC : 1/2
> IMSI : 901700000003080
> Ki : 7edaeb6addbd72d2b2cc6ed7bfecc9c9
> OPC : 23f075ab9b1a113d4db822d8195ea20c
> ACC : None
Programming ...
Done !

12. Example to program a SysmoUSIM-SJS1 (orange) card

(U)SIM cards are Java capable and there is the Globalplatform that specifies standards API. SMS can be addressed directly to the SIM card, the SIM card will get events for network selection and others, it can modify call establishment attempts.

Provisioning of different identities or keys.

If you have a variant of the card-individual ADM1 key of your sysmoUSIM-SJS1 card, you can change any identity (IMSI, ICCID, MSISDN) stored on the (U)SIM, as well as the private key data (K, OPC).

ADM1 key can be found at:

[https://openerp.sysmocom.de/web#page=0&limit=80&view_type=list&model=sysmocom.simcard&menu_id=679&action=912]

In the below example, we are changing the card’s IMSI to 901710000011000 (it was 901700000011000 before), and specify a
new set of K and OPC values.

$ ./pySim-prog.py -p 0 -t sysmoUSIM-SJS1 -a 58001006  -x 901 -y 71 -i 901700000010659 -s 8988211000000110000 -o 398153093661279FB1FC74BE07059FEF -k 1D8B2562B992549F20D0F42113EAA6FA
Insert card now (or CTRL-C to cancel)
Generated card parameters :
> Name : Magic
> SMSP : e1ffffffffffffffffffffffff0581005155f5ffffffffffff000000
> ICCID : 8988211000000110000
> MCC/MNC : 901/71
> IMSI : 901700000010659
> Ki : 1D8B2562B992549F20D0F42113EAA6FA
> OPC : 398153093661279FB1FC74BE07059FEF
> ACC : None
Programming ...
Done !

13 README

pySim comes with following README file:

This utility allows to :

  • Program customizable SIMs. Two modes are possible:

- one where you specify every parameter manually :

./pySim-prog.py -n 26C3 -c 49 -x 262 -y 42 -i <IMSI> -s <ICCID>

- one where they are generated from some minimal set :

./pySim-prog.py -n 26C3 -c 49 -x 262 -y 42 -z <random_string_of_choice> -j <card_num>

With <random_string_of_choice> and <card_num>, the soft will generate
'predictable' IMSI and ICCID, so make sure you choose them so as not to
conflict with anyone. (for eg. your name as <random_string_of_choice> and
0 1 2 ... for <card num>).

You also need to enter some parameters to select the device :
-t TYPE : type of card (supersim, magicsim, fakemagicsim or try 'auto')
-d DEV : Serial port device (default /dev/ttyUSB0)
-b BAUD : Baudrate (default 9600)

  • Interact with SIMs from a python interactive shell (ipython for eg :)

from pySim.transport.serial import SerialSimLink
from pySim.commands import SimCardCommands

sl = SerialSimLink(device='/dev/ttyUSB0', baudrate=9600)
sc = SimCardCommands(sl)

sl.wait_for_card()

  1. Print IMSI
    print sc.read_binary(['3f00', '7f20', '6f07'])
  1. Run A3/A8
    print sc.run_gsm('00112233445566778899aabbccddeeff')
